This book contains five articles which examine the areas of administration and instructional design, as well as the technical components of a teleconferencing system; included is an annotated bibliography on telephone education/communications which lists articles on research and theory, administration, technical components, instructional design, case studies, and teleconferencing systems. The instructional design articles focus on the ingredients of program design which maximize effectiveness of an interactive audio system. Research in listening, learning, communications, group interaction, and adult education is related to successful teaching techniques developed by instructors experienced in teaching via telephone. The articles on administration explore the overall organization of a teleconferencing system and present an overview of a modal system, with emphasis on program promotion, registration procedures, local site facilitators, and evaluation methods. The technical article describes the requirements and general design criteria for a system for teleconferencing, including the station equipment, the control center, and the transmission system. Practical solutions to problems encountered during the development and implementation stages of teleconferencing systems are suggested. (Author/CMV)
